Searching for 2, 3, 4 character ACRONYMS within a large document

rmacarthur — Sat, 15 Jul 2017 13:16:29 GMT

HI All,

I have base SAS, E.G., SAS Studio, and

Need to search a large document for all acronyms (2, 3, 4 character), isolate them, and create a table of definitions.

The acronyms can be any character like "IND", "mg", 'USP", etc...

Is there a SAS function , or combination of functions, that will count the number of characters in a word, and provide a YES/NO (1/0) answer if a certain number of characters are present?

Thanks

It's easy to count the number of characters in a word:

n_characters = lengthn(varname);

I'm not sure you gain anything by translating this into a YES/NO. You can easily select a subset that you want:

if n_characters = 3;

if 0 < n_characters < 3;

or anything else that you would select. Possibly:

proc freq data=have;

tables varname;

where (0 < lengthn(varname) < 3);

run;
